我们如何创建带有列列表的 MySQL 视图？

As we know that while creating a view, providing the list of columns is optional. But if we are providing the name of the columns while creating the view then the number of names in the list of columns must be the same as the number of columns retrieved by the SELECT statement.

Example

The following example will illustrate by creating the views with column list −

mysql> Select * from student_detail; +-----------+-------------+------------+ | Studentid | StudentName | address | +-----------+-------------+------------+ | 100 | Gaurav | Delhi | | 101 | Raman | Shimla | | 103 | Rahul | Jaipur | | 104 | Ram | Chandigarh | | 105 | Mohan | Chandigarh | +-----------+-------------+------------+ 5 rows in set (0.17 sec) mysql> Create view View_student_detail_columns AS SELECT Studentid, StudentName FROM Student_Detail; Query OK, 0 rows affected (0.10 sec)登录后复制

mysql> Select * from View_Student_detail_columns; +-----------+-------------+ | Studentid | StudentName | +-----------+-------------+ | 100 | Gaurav | | 101 | Raman | | 103 | Rahul | | 104 | Ram | | 105 | Mohan | +-----------+-------------+ 5 rows in set (0.08 sec)登录后复制
